Use of Non-GAAP Measures

Management believes that adjusted EBITDA and free cash flow are useful measures of operating performance because they exclude items that we do not consider indicative of our core performance. In the case of adjusted EBITDA, we adjust net income for such things as interest, taxes, stock-based compensation and certain non-cash and non-recurring items. Free cash flow subtracts from adjusted EBITDA the capitalization of content database costs, capital expenditures and cash paid for income taxes and interest expense. However, these non-GAAP measures should be considered in addition to, not as a substitute for or superior to, net income and net cash provided by operating activities, or other financial measures prepared in accordance with GAAP. A reconciliation to the GAAP equivalents of these non-GAAP measures is contained in tabular form on the attached unaudited financial statements.

Our management uses adjusted EBITDA and free cash flow as measures of operating performance; for planning purposes, including the preparation of our annual operating budget; to allocate resources to enhance the financial performance of our business; to evaluate the effectiveness of our business strategies; to provide consistency and comparability with past financial performance; to facilitate a comparison of our results with those of other companies; and in communications with our board of directors concerning our financial performance. We also use adjusted EBITDA and have used free cash flow as factors when determining the incentive compensation pool.
